PRISM, a Bidirectional NMR Foundation Model: From Peak List to Structure and Back

Angewandte Chemie, EarlyView.
Structure elucidation from NMR can consume an expert for hours or even days. PRISM addresses this with a bidirectional transformer trained on 1.19 M real experimental spectra: it translates 1H and 13C peak lists into structures with 60.1% stereo‐aware top‐1 accuracy (72.5% stereo‐unaware), and, working in reverse, predicts spectra back from structures,

Sequence‐Controlled Helical Ladder Polymers: Impact of Stereochemical Sequence on Helical Geometry and Chiral Recognition

Angewandte Chemie, EarlyView.
Nature programs distinct secondary structures and functions through subtle stereochemical differences, as exemplified by amylose and cellulose. Translating this principle into synthetic ladder polymers, stereochemical sequence control gives rise to diastereomeric coil‐ and ribbon‐type helices with complementary chiral recognition, demonstrating ...

NHC‐Copper(I)‐Mediated Functionalization of White Phosphorus

Angewandte Chemie, EarlyView.
White phosphorus is functionalized by N‐heterocyclic carbene supported copper(I) complexes through redox‐neutral steps. Treatment of the resulting complexes with electrophiles releases the ligands from the metal center as asymmetrically substituted organophosphorus butterfly compounds.

Oxygen‐Tolerant, Controlled Synthesis of Degradable and Water‐Soluble Poly(Vinyl Amide)s via Radical Ring‐Opening Copolymerization of Cyclic Dithiothreitol

Angewandte Chemie, EarlyView.
Oxygen‐tolerant photoinduced electron/energy transfer reversible addition–fragmentation chain transfer (PET‐RAFT) polymerization enables the controlled radical ring‐opening (rROP) copolymerization of cyclic dithiothreitol (cDTT) with less‐activated vinyl monomers, affording degradable polymers with predictable molecular weights, low dispersities, and ...
